Probiotic Effect

Sourdough bread is a traditional product, which is produced by mixing wheat, rye or other grain flours with water and lactic acid fermentation. The supposed mechanisms for the effect of foods produced by sourdough fermentation on health were probiotic effect of microorganisms, production of bioactive peptides and organic acids (acetic acid, butyrate, propionic acid), decreased amount of anti-nutrients (phytic acid, etc.), digestibility of starch and protein, increased bioaccessibility of phenolic compounds and bioavailability of minerals, degradation of gluten, new product to celiac patients. It was reported to have effects on nutrition, such as product development. In this review, the effect of sourdough fermentation on the ingredients in bread, in vitro bioaccessibility and health benefits are examined.

AbstractImproving the nutrition of livestock is an important aspect of global food production sustainability. This study verified whether lactic acid bacteria (LAB) inoculant could promote ensiling characteristics, nutritive value, and in vitro enteric methane (CH4) mitigation of forage sorghum (FS) mixture silage in attacking malnutrition in Zebu beef cattle. The FS at the soft dough stage, Cavalcade hay (CH), and cassava chip (CC) were obtained. The treatments were designed as a 4 × 2 factorial arrangement in a completely randomized design. Factor A was FS prepared without or with CH, CC, and CH + CC. Factor B was untreated or treated with Lactobacillus casei TH14. The results showed that all FS mixture silages preserved well with lower pH values below 4.0 and higher lactic acid contents above 56.4 g/kg dry matter (DM). Adding LAB boosted the lactic acid content of silages. After 24 h and 48 h of in vitro rumen incubation, the CC-treated silage increased in vitro DM digestibility (IVDMD) with increased total gas production and CH4 production. The LAB-treated silage increased IVDMD but decreased CH4 production. Thus, the addition of L. casei TH14 inoculant could improve lactic acid fermentation, in vitro digestibility, and CH4 mitigation in the FS mixture silages.

Increasing Demand

Preventing food spoilage without the addition of chemical food additives, while increasing functional properties of wheat-based bakery products, is an increasing demand by the consumers and a challenge for the food industry. Within this study, lactic acid bacteria (LAB) isolated from sourdough were screened in vitro for the ability to utilize the typical wheat carbohydrates, for their antimicrobial and functional properties. The dual culture overlay assay revealed varying levels of inhibition against the examined fungi, with Lactiplantibacillus plantarum S4.2 and Lentilactobacillusparabuchneri S2.9 exhibiting the highest suppression against the indicator strains Fusarium graminearum MUCL43764, Aspergillus fumigatus, A. flavus MUCL11945, A. brasiliensis DSM1988, and Penicillium roqueforti DSM1079. Furthermore, the antifungal activity was shown to be attributed mainly to the activity of acids produced by LAB. The antibacillus activity was evaluated by the spot-on-the-lawn method revealing a high inhibition potential of the majority of LAB isolated from sourdough against Bacillus cereus DSM31, B. licheniformis DSM13, B. subtilis LMG7135, and B. subtilis S15.20. Furthermore, evaluating the presence of the glutamate decarboxylase gen in LAB isolates by means of PCR showed a strain dependency of a potential GABA production. Finally, due to improved functional activities, LAB isolated from sourdoughs exhibit promising characteristics for the application as natural preservatives in wheat-based bakery products.

Butyric Acid Fermentation

A comparatively slight increase in environmental osmotic pressure inhibited the in vitro development of butyric-acid bacteria [Clostridium spp.], especially with increasing H-ion concentration. Sub-lethal concentrations of salt (NaCl, KCl, Na2SO4) and/or H-ions retarded the start of clostridial development and reduced the quantity of butyric acid produced. In wilted grass silage it was shown that osmotic pressure plays a considerable part in repressing butyric-acid fermentation in the initial stages of silage fermentation. Low temperature (< 20-25 degrees C.), low pH (< 4.2), high lactic-acid content and high osmotic pressure were more harmful to clostridia than to lactic-acid bacteria.-R.B.
